Des Moines police say 45-year-old Robert William Webb was arrested Wednesday. He faces charges of carrying weapons and unauthorized possession of offensive weapons. Court records do not list an attorney.

A witness told police that he saw Webb arguing with a couple before he later appeared alone with a revolver in his hand.

Webb is accused of loading the gun and walking around a neighbor's house and looking around.

The Des Moines Register reports police found Webb on his porch, sitting in a lawn chair with a revolver next to him. Authorities confiscated additional weapons in Webb's house.

Hillary Clinton did not have a State Department email account while she served as America's top diplomat, a senior state department official said Monday, and instead used a personal email account during her four years on the job.
